Troubleshooting
If Wicd fails to connect after you install it, make sure that the only entry in your /etc/network/interfaces file is
auto lo
iface lo inet loopback
You can change the contents of this file by pressing alt + f2, then typing gksudo gedit /etc/network/interfaces if you are using Gnome, or replace gedit with kate if you are using KDE. This will allow you to view and edit the /etc/network/interfaces.You can ignore lines that start with #.
